Answer

Explanation:

Step1: Recall mechanical - advantage formula

The mechanical advantage (MA) is calculated as $MA=\frac{\text{Output force}}{\text{Input force}}$.

Step2: Calculate MA for Brian

$MA_{Brian}=\frac{300}{150}=2$.

Step3: Calculate MA for Lian

$MA_{Lian}=\frac{350}{400}=0.875$.

Step4: Calculate MA for Dipak

$MA_{Dipak}=\frac{450}{250}=1.8$.

Step5: Calculate MA for Aida

$MA_{Aida}=\frac{375}{300}=1.25$.

Step6: Arrange in ascending order

$0.875 (Lian)<1.25 (Aida)<1.8 (Dipak)<2 (Brian)$.

Answer:

Lian, Aida, Dipak, Brian
